目的:随机化,对照试验表明,运动干预可降低糖耐量受损人群2型糖尿病的发病率,改善血糖控制,2型糖尿病患者的身体成分和心肺健康。我们进行了本系统评价,以确定结构化运动试验的参与者在干预结束后继续进行身体活动的程度。
方法:我们系统地搜索了MEDLINE,EMBASE,CINAHL,SPORTDiscus和Cochrane中央随机对照试验注册,对照试验报告了2型糖尿病或糖尿病前期患者在结构化运动干预结束后至少3个月的客观或自我报告的身体活动水平。本系统综述在PROSPERO(PROSPEROCRD42018089468)上注册。
结果:在检索到的14649篇文章中,5随机,本系统综述纳入了对照试验(包括549名参与者).一项研究显示,基线评估后1、3和5年,与对照组相比,干预组自我报告的身体活动水平显着改善。腰围减少,1年体重和体重指数,但不是3年或5年。其余4项研究在6个月至3年的随访时间点未发现组间差异。
结论:未来的研究应在随访时报告身体活动水平,以确定参与结构化运动干预是否会导致身体活动水平持续增加。此外,应评估干预措施在提高长期体力活动依从性方面的有效性.
OBJECTIVE: Randomized, controlled trials have shown that exercise interventions reduce the incidence of type 2 diabetes in people with impaired glucose tolerance, and improve glycemic control, body composition and cardiorespiratory fitness in people with type 2 diabetes. We undertook the present systematic
review to determine the extent to which participants in structured exercise trials continue to be physically active after the end of the interventions.
METHODS: We systematically searched MEDLINE, EMBASE, CINAHL, SPORTDiscus and Cochrane Central Register of Controlled Trials for randomized, controlled trials that reported objective or self-reported physical activity levels in people with type 2 diabetes or prediabetes a minimum of 3 months after the end of a structured exercise intervention. This systematic
review was registered on PROSPERO (PROSPERO CRD42018089468).
RESULTS: Of 14,649 articles retrieved, 5 randomized, controlled trials (including 549 participants) were included in this systematic
review. One study revealed significant improvements in self-reported physical activity levels in the intervention group compared with the control group 1, 3 and 5 years after baseline assessments, and decreased waist circumference, weight and body mass index at 1 year, but not 3 or 5 years. The 4 remaining studies did not find between-group differences at follow-up timepoints between 6 months and 3 years.
CONCLUSIONS: Future research should report physical activity levels at follow up to determine whether participation in a structured exercise intervention results in sustained increased physical activity levels. In addition, interventions should be evaluated for their effectiveness in improving adherence to long-term physical activity.
